  • Power quality indices measurement using the S-transform

    The paper presents the S-transform (ST) technique as a new tool for power quality indices measurement. A key feature of the ST is its accurate time-frequency (amplitude and phase) domain. With this feature, it is possible to redefine the calculation of the power quality indices in the ST domain based on the harmonic content of the signals. In addition, using the time information provided by this ...

  • Characterisation of power quality disturbances based on wavelet transforms

    This paper presents a new technique for detecting and characterising disturbances in power systems based on wavelet transforms. The voltage signal under investigation is often corrupted by noises, therefore the voltage signal is first denoised using wavelet thresholding and then wavelet transform is applied to the denoised signal. Using the first-level detail wavelet coefficients, the voltage ...

  • Transformer oil quality control

    It is impossible to ensure reliability and longevity of energy systems without controlling the quality of transformer oil. Recent experience shows that approximately 30% of transformer oil, filled in power transformers, has deteriorated to the point when it becomes a risk factor. This is caused both to natural degradation of oil in operation due to thermal oxidation aging, and contamination with ...

  • The Transformation of International Environmental Law

    Keywords: International environmental law, environmental law, global challenges, harmoni-sation and common interests 2012 is the fortieth anniversary of the Stockholm Conference on the Human Environ-ment, a seminal event which marked the first time that the international community had addressed the environment as an international issue in a serious way. Back in 1972, the Conference called ...


  • On-site regeneration of transformer oil

    Regeneration of transformer oil at the transformer’s location is an important preventive measure of transformer servicing.   Transformer life time is, in essence, the life time of its insulation system. The most widely used insulation is liquid insulation (transformer oils) and solid insulation (paper, i.e. cellulose insulation). The oil provides for at ...

  • Magnetising inrush current in transformers: an overview

    In India, the failure rate of distribution transformers has been reported very high especially in the rural and remote areas. In these areas, frequent inrush current is produced in distribution transformers during their energisation. The generation of inrush current during each energisation may be dangerous for health of the distribution transformers. This has motivated the authors for extensive ...

  • How Does Solar Energy Transformed into Electricity?

    Many years ago, solar energy was never been the subject of all talks. Basically because the solar energy was never given that importance in people’s day to day life before. They just ignore and did not give attention on its importance. They fail to realize the importance of it. Now, as the period of modernized society where new technologies and innovations occurred came, the demand for ...

  • Regression analysis for insulation failures in transformer windings

    The winding insulation system is the main component of power transformers. If there is any failure in winding insulation will have a crucial impact of the energy system operation. Insulation failure is the predominant part of faults and highest risk for all types of transformer failures. Most of the winding insulation failure is primly due to partial discharge. Partial discharge identification is ...
